If the monitor on the ideacentre has an input then you should be able to do that. You could use a VGA, DVI, or HDMI connector depending on what is available. If it does not have additional ports for input then you won't be able to do this.

The HDMI receptacle on the PC portion is for output.

I have 2 PCs connected to one monitor here. I can switch between them with an input button on the monitor. That would also be very important to have. Standard PC monitors have these. I'm not sure about All-In-Ones.

In case you don't have any input in that ideacentre, you can install some softwares (a free one, a paid one with more features) that disguise themselves as a video card and pass the screen data through LAN, so it will totally suck for decent games but will be fine for everything else (well maybe HD movies may suffer, don't know, you can try the free one and see).

Cool. But the problem is that since the Ideacentre is an all-in-one PC, my laptop monitor may end up displaying my Ideacentre desktop, but I want it to be the other way round.

i think there would be some problems
first check if the HDMI is an input port on lenovo, the hdmi port on your lenovo may be an output port the same as HDMI port on your laptop.can you take a photo from the back panel of your lenovo here?
